The answer is 44
2 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 106
if ((18-18)/(12-14))**0.5 = 0 if (18-(18/12)-14)**0.5 = 1.58113883 if (18-18/(12-14))**0.5 = 3 if ((18-18)/12-14)**0.5 = 0
14 + 18 = 18 + 14 demonstrates the commutative property (of addition).
18 + 14 = 32
18 plus 4, minus 2
-6
18 inches = 18/12 ft 14 inches = 14/12 ft (18/12) x (14/12) = (18 x 14) / (12 x 12) = 252/144 = 1.75 ft2
4
12+14+18 = 44
18 - 12 - 14 = -8
12 + 14 + 3 = 29
14 + 12 + 34 = 60
